1964 Alaska earthquake

This 1964 earthquake is notable for its tremendous magnitude of 9.2, which caused widespread devastation across south-central Alaska. The seismic event triggered massive ground fissures, structural collapses, and tsunamis that resulted in approximately 139 fatalities. Its impact led to major advancements in seismic engineering and the understanding of plate tectonics.

The term has recently re-emerged in news headlines following a significant seismic event. In late November 2025, a 6.0 magnitude earthquake struck the Anchorage area, representing the largest tremor to hit the region in several years.

While this recent earthquake was substantially less powerful than the 1964 event, it caused noticeable shaking and served as a reminder of Alaska's persistent seismic hazard. The event drew international media coverage and renewed attention to the region's earthquake preparedness measures.
